“Let me try again, please.” Shoto asked you, his eyes so sweetly earnest.
“What now? Here?” You were finishing up your sidekick work at the Endeavor agency.
“Why not? It’s late, we’re probably the last two here.” You chewed on your lip, thinking about how badly you wanted a release, one that had evaded you for a long time.Â
“I dunno, Sho. If we get caught-”
“We won’t get caught if you’re quiet.” He toyed with the hem of your costume’s skirt and brushed his cool fingertips over the soft skin of your inner thigh.
“Ok, but don’t be upset if I can’t finish.”Â

Endeavor’s flames burned lazily from where he sat at his desk, his whole body exhausted from another day of hero work. He scrubbed a hand over his face, and realized how badly he needed to shave. The rest of the paperwork could wait until morning, he decided. So, he gathered his stuff and began making his way out of the building. He was just about to leave when he swore he heard a tiny whimper from somewhere deeper in the building.Â
“Dammit.” He headed in the direction of the noise to investigate. The building was usually empty by that time of night, but the soft sobs persisted, getting louder with every step he took. Endeavor rounded the corner to the sidekick’s office, when he stopped short in the shadows. His brain must have been short-circuiting (maybe the flames finally cooked it?) Spread out on the closest desk before him was you, one of his sidekicks. And down bobbing his head between your legs was his youngest son, Shoto.Â
“Shoto, please..” You panted out, your muscles clenching, trying to help your orgasm along.
Endeavor couldn’t help himself, he palmed his suddenly agonizingly hard cock through his costume. He’d always had a soft spot for you and deep down he knew it was because he was attracted to you. He always loved how your soft and shy demeanor hid your immense raw power. He loved how you smiled at him even when he didn’t deserve it. He wanted you, and apparently his son wanted you in the exact same way. A sort of gross jealousy made his flames crackle a little, seeing his son have another opportunity that he himself would never get.Â
“Shotoooooo.” You were practically wailing, your exposed breasts heaving with frustration. “Please, I’m close.” You were close to tears, feeling your orgasm build but never break was a special kind of torture that you could never get used to. Shoto worked his tongue eagerly over your softness, encouraged by your words. In his excitement, his rhythm faltered a little and you couldn’t help but groan in disappointment.Â
“I’m sorry.” He sighed, hiding his face in your thigh. “I didn’t mean to.” He looked up at you self-consciously, his mouth and chin dripping with your wetness. That sight almost made up for the ruined orgasm. Almost.
“It’s not your fault.” You sighed. “It’s impossible.” You held your face in your hands, trying to hide just how upset you were from him.
“Hey,” he said, pulling your hands away to cradle your face to his chest. “I’ll go all night if I have to.” It was a promise, determination flashed brightly in his eyes.
“You want me to finish her off for you?” Endeavor’s deep voice startled the two of you from the shadows. “I don’t want you to be here all night.” You reached for your costume to cover yourself, but it must have fallen behind the desk. Endeavor finally emerged from the darkness. His eyes raked across your flesh and you burned. Burned with embarrassment of getting caught and the shame of liking it.Â
“Dad!” Shoto cried out, wiping his face on his sleeve and stepping in to shield you. Shoto processed his father’s words for a moment before realizing what he actually said. “What the fuck? No, I don’t want you to finish her.”Â
“But I could teach you how.” Endeavor offered, his words ringing filthily in everyone’s ears. Shoto froze in place and remained silent for a moment. He couldn’t possibly be thinking about it, could he? You thought, a wicked sort of anticipation coursing through you. Shoto finally glanced back at your trembling form, his eyes conflicted.Â
“If you mean that, if you swear you can make her cum, then go ahead.” Shoto conceded, never taking his eyes off yours.Â
“What?” You chime in dumbly. “What is happening?”Â
Endeavor approached you where you were still perched on the desk. “Open your legs for me.” It was a command, but his voice was softer than normal, almost tender even. It made you want to obey. With a shaky breath, you parted your thighs, revealing the most intimate parts of yourself to the number 1 hero. To your lover’s father.Â
“I’m glad to know you’re doing something right, Shoto.” Endeavor chuckled, running a long finger between the throbbing soaked mess of your folds. “Or are you just that desperate for it, (Y/N)?” You choked out a gasp as he brought his thumb down roughly on your sore clit. “Answer me when I speak to you.” He reached his other hand to grasp under your chin, his fingers prodding painfully at your jaw.Â
“O-okay.” You were beyond nervous. You had always been intimidated by Shoto’s father, even after you joined his hero agency. And the prospect of him making you cum…had you in shambles.Â
“Are you a desperate little slut?” Endeavor asked again.Â
“Don’t call her names.” Shoto warned from his spot beside the desk. Endeavor slipped the tip of his finger up to probe at your entrance, swirling it around your hole.
“I can’t help it, listen to how needy she’s being.”Â
“Mhmmm-” Was the best response you could give while your pussy was being teased so ruthlessly. Endeavor chuckled darkly at your red hot face before kneeling down between your legs. His tongue took up Shoto’s work lapping around your clit as he slid his finger in deeper between your wet walls. “Aaahh.” You cried out, pulling your heels up onto the desk to give Endeavor better access.Â
“What a good girl.” Endeavor praised between slow passes at your trembling bud. “Have you ever had an orgasm before?” You shook your head, embarrassed. “If you want me to make you cum, say my name.” He took an absolutely sinful amount of pleasure tasting you, waiting to hear his name fall from your lips.Â
“En-endeavor.” You squeaked out pitifully through your heaving breaths.Â
“No.” He ripped his mouth away and retracted his finger leaving you untouched and aching. “My name. Enji.” He corrected sternly. You glanced over at Shoto, seeking permission for something that felt so impossibly filthy, you would be shocked if he granted it to you. “Don’t look at him. Right now, you’re mine.”
“Okay…Enji.” With a satisfied smirk, Endeavor continued his tantalizing treatment of your puffy pussy, building up that pressure in your core slowly. He added a second finger to better caress your insides, pushing up on your front wall until he’d pinpointed your softest, spongiest spot. “Oh god.” You felt an odd sensation, like you were going to come undone. Be unmade by his too-big fingers in your tight cunt. Melt beneath his fiery lips until you were reduced to a puddle wetting every surface of the desk.Â
Your legs shook uncontrollably, Endeavor used his free hand to keep you in place. Your walls contracted around his fingers and he pushed back against them, targeting that precious spot until you were babbling his name frantically. White hot liquid splashed out around his fingers and coated his face and beard as your lungs let out one last cry, your very first orgasm wracking through your entire body. You fell back against the desk, seeing stars and trying to remember how to breathe.Â
“(Y/N).” You felt the hair being brushed back from your damp forehead. “(Y/N) did you finish?” Shoto asked quietly.Â
“Of course she did.” Endeavor said, tasting your remaining sweetness on his lips. “And she’s not done. Come here.” He motioned for Shoto to join him between your legs. Shoto hesitated for a moment before giving into his desire to make you cum no matter what. “Slip your index finger into her.” Shoto did, moaning at how soft and pliant his dad had made you.Â
“Wait-” You choked out. “I’m still coming down.”Â
Endeavor ignored you and added his own finger under Shoto’s and guided his son’s finger to your g-spot. “Do you feel that? How it feels different?” He coaxed Shoto’s fingers into a soft stroking motion, earning a loud moan from you.Â
“Yes.” Shoto’s voice grew excited as he took over the motion on his own.Â
“Now take your thumb and put it here.” Your clit pulsed painfully from the overstimulation. “Use gentle pressure when you’re rubbing it. She doesn’t need a lot to turn into a sloppy little mess.”
You looked up to both sets of eyes fixated on you, watching you writhe beneath their fingers. They could see everything from that angle, the way your greedy pussy sucked them in, the way your face would contort when you came a second time.Â
“Sho…I can’t. Not again. Not like this.” You reached out to stop their hands.
“Do I need to hold you down?” Endeavor threatened with a sharp little smack to your thigh.Â
“N-no, Enji.” Shoto’s finger halted inside you, unsure of what to do.
“Keep going Shoto, we’ll have her cumming in no time.” They resumed, but Endeavor switched up his rhythm to be opposite of Shoto’s, scissoring your little hole open as lewd squelching sounds filled the office. True to Endeavor’s words, after just a few moments you felt yourself on the edge of your second orgasm. You keened wildly and your vision blurred until your hole finished pulsing around their sopping fingers.    Â
“She didn’t squirt.” Shoto said, disappointment clear in his voice.
“That’ll take some practice.” His father chuckled before shucking off his hero costume, standing fully naked.Â
“What are you doing?” Shoto asked warily.
“She’s not done until she cums on my cock.”Â
“Absolutely not. You don’t get to fuck her.” The wetness on Shoto’s fingers frosted over as his quirk activated.Â
“Do you want my cock, (Y/N)?” You looked down at his massive dick, its pulsing red tip leaking a long string of precum down to the floor. It terrified you, you had never taken anything so big…but the sight also made your cunt spasm with need.
“I’m sorry Sho.” You whined out. “I want it. Can I please?” Shoto averted his eyes, he didn’t think he could watch, but he wasn’t in the habit of denying you things you wanted.Â
“Get it wet for me.” Endeavor guided you to your knees in front of him, his length bobbing in front of your face. You flicked your tongue curiously over the saltiness of his slit before suctioning the head between your lips. He threw his head back with a groan. You couldn’t fit much more of his length down your throat, so you settled from licking up the shaft, messily coating it in saliva.Â
“Such a good girl.” Endeavor murmured before hauling you back up into your position on the desk. “Do you want it like this?” He slid his tip up to your entrance, pushing it past the first ring of muscle. “Or do you want me to flip you over and take you from behind?”Â
“Ummm…” You hummed out dumbly. The sight of Endeavor’s cock penetrating you was making you lust drunk.Â
“Guess it’s my choice.” He said gruffly before spinning you around and pressing your tits to the cool metal of the desk. Your pussy strained against his veiny shaft as he pressed deeper into you. It was heavy and hotter than you imagined, flames licked up your insides, opening the path for his cock.Â
Shoto approached you from the other side of the desk despite his better judgment. His fist pumped his cock agitatedly. “Will you open?” He asks you shyly. You oblige him, feeling his veins slide onto your tongue. You give him a few exhausted bobs before he knots his hands in your hair and takes control, fucking your face harder than he ever had before. Not to be outdone, Endeavor continued to split you open, setting a pace that would surely bruise your insides.Â
“Show me what a good girl you are and take it all, ok?” Endeavor grunted as he stuffed your pussy so full you were screaming around Shoto’s cock. Your poor little walls fluttered weakly against him, trying to push him out.Â
“Ennnjiiii. Can’t.” Your words were so muffled he either couldn’t hear you or didn’t care. And just like that you were snapping once more, creaminess coating the base of Endeavor’s cock and dripping down to soil the discarded documents on the floor.Â
“There you go.” Endeavor stroked your back as you cried through the final few waves of pleasure. “Gonna fill you to the brim with my cum.”Â
“The fuck you will.” Shoto growled, his thrusting was erratic as he hit the back of your throat wickedly. The head of his cock was nestled down to deposit his own semen deep into you.Â
“Are you going to quit fucking her throat to stop me?” Endeavor’s pace turned animalistic, his hands crushing the delicate skin of your hips as he forced you back even farther until his cock was punching your cervix. All Shoto could do was groan in response as his dick twitched and released his load. His hot cum dripped down your sore throat as Endeavor pummeled you from behind once, twice, three times more and was spurting his fiery seed inside your womb.
You were burning at each end. They had used up all of you, you couldn’t think, couldn’t breathe.Â
“Are you fucking breeding her?” Your lover’s angry voice brought you back down to reality and you realized his father hadn’t pulled out yet.Â
“You relinquished this pretty pussy to me, I’ll do what I want with it.” Endeavor said finally, planting a messy kiss on the column of your spine.
